Add Custom Exception Handler to Unwrap `CompletionException` for GraphQL Instrumentations #10389

mhlidd · 2026-01-15T21:37:34Z

What Does This Do

Currently, if async calls done in the GraphQL result in exceptions, the integration will return the exception wrapped in a CompletionException. This PR instruments the DataFetcherExceptionHandlerParameters.getException method to unwrap the exception of any CompletionException before sending the exception to GraphQL's DataFetcherExceptionHandler.

Note that GraphQL's basic implementation of their DataFetcherExceptionHandler already unwraps one layer of CompletionException.

I would want to make sure there are no issues with unwrapping in all possible cases. Perhaps keeping the original exception would be helpful for keeping context of where the original exception occurred in the stack trace, because unwrapping will only keep the inner exception's stack trace. Otherwise if this is not a concern, then LGTM
